Using the principle of binomial probability, the probability that more than 3 friends win a prize is
Recall :
- P(x = x) = nCx * p^x * q^(n-x)
<u>Given</u><u> </u><u>the</u><u> </u><u>Parameters</u><u> </u><u>:</u>
- <em>Probability</em><em> </em><em>of</em><em> </em><em>success</em><em>,</em><em> </em><em>p</em><em> </em><em>=</em><em> </em><em>1</em><em>/</em><em>6</em><em> </em>
- <em>q</em><em> </em><em>=</em><em> </em><em>1</em><em> </em><em>-</em><em> </em><em>p</em><em> </em><em>=</em><em> </em><em>5</em><em>/</em><em>6</em><em> </em>
- <em>Number</em><em> </em><em>of</em><em> </em><em>trials</em><em>,</em><em> </em><em>n</em><em> </em><em>=</em><em> </em><em>7</em>
- <em>x</em><em>≥</em><em>3</em><em> </em>
Hence,
P(x ≥ 3) = p(x = 3) + p(x = 4) + p(x = 5) + p(x = 6) + p(x = 7)
P(x ≥ 3) = 0.0781 + 0.0156 + 0.0019 + 0.0001 + 0.000003
P(x ≥ 3) = 0.095703
Therefore, the probability that more than 3 friends win a prize is 0.0957

Answer:
Big-O Notation,Omega Notation,Theta Notation
Explanation:
Big O notation specifically describes worst case scenario.
Omega(Ω) notation specifically describes best case scenario.
Theta notation represents the average complexity of an algorithm.
Answer: The correct answer is C.
Explanation:
Motorcyclists have to make themselves more visible at night by suing reflective tape both on the back of the helmet and in their clothes. Reflective tape is an adhesive, whose surface reflects light. You will be spotted immediately by a car passing by without any danger to drivers.
High beams are <em>only</em> used at night when you're unable to see the road in certain situations. If motorcycliests use them most of the time, this can improve the risk of blinding others on the road.
Both driving at slower speeds and in the center of the lane don't make motorcyclists more visible. They won't be spotted in the middle of the night until they are pretty close, which is going to be too late.
